TwitterBox seems to be my second most used Twitter app at the moment. If you are one of those people that follows A TON of people, but still actually wants read you family, friends, news or other Twitter accounts? Then this might be an app to consider. TwitterBox allows you to sort the people (an searches) you are following into categories (known as Boxes in-app). It is a quick and and intuitive application that also includes all the standard features of Twitter. As a plus it also has Auto-updating. [$1.99 – iTunes link]
